Title: Control device of variable pressure regulator for internal combustion engine
Inventor: YAMAMOTO NAOKI
IPC: F02M69/00
Filed: 1998-07-24
Abstract: PROBLEM TO BE SOLVED: To avoid malfunction caused by biting of foreign materials between a valve element and a valve seat, or adhesion of abraded powder in a control device. SOLUTION: A duty ratio of a driving pulse signal is controlled (step 5) according to a target fuel pressure during normal operation (step 2), and an opening of a valve body is regulated. Pressurized fuel is partially leaked through the pressure regulator. When the duty ratio is increased, the fuel pressure is lowered. During deceleration accompanying cutting fuel (step 3), scavenging mode is executed. A scavenging pulse signal of large frequency is transmitted so that large and small liftings of the valve body are repeated (step 8). An ON duty ratio of repetition number of the scavenging pulse signal are set according to the immediately previous operation conditions (step 7). When abnormal lowering of the fuel pressure is sensed, the scavenging mode is immediately executed based on the specified duty ratio and repetition number even without deceleration (step 10).

Title: Liquid developing device
Inventor: OIKAWA NOBURO
IPC: G03G15/10
Filed: 1988-08-22
Abstract: PURPOSE:To reproduce uniform solid black print without any absence by proving a sleeve which conveys liquid toner to a development area and a thin film which controls the liquid surface of the liquid toner in the development area and has through holes. CONSTITUTION:When a developing sleeve 3 is rotated, the liquid toner 4 is conveyed to the development area while held by a toner holding layer 2. The toner holding layer 2 is compressed by a developed film 1 and the developing sleeve 3 and the liquid toner 4 enters through holes 5. Its pressure is higher than the atmospheric pressure, but the toner 4 does not spread uniformly on the surface of the developed film 1 because of the surface of the developed film 1 is hydrophobic and swells only at the parts of the through holes 5. Therefore, all swells of the liquid toner 4 facing an electrostatic latent image 6a begin to be absorbed at the solid black part and swells of the liquid toner 4 facing electrostatic latent images 6b and 6c are absorbed by the latent images where the electrostatic latent images are close to each other. Consequently, uniform solid black print having no absence and fine development having no blur are realized.

IPC: G03G15/00
Filed: 1989-08-10
Abstract: PURPOSE:To stabilize image quality for a long time by allowing an electrostatic charging quantity control means to control charging quantity when image forming frequency exceeds a prescribed value. CONSTITUTION:An operation panel 100 and a counter for counting up image forming frequency are connected to a CPU 201 and the CPU 201 recognizes a copying condition set up by an operator based upon the input results of respective key switches on the operation panel 100 and decides the time for controlling the charging quantity in accordance with the input result of the counter 203. Namely, the means for allowing the charging quantity control means to control the charging quantity when the count value of the counter 203 exceeds the prescribed value is prepared. Even when the surface potential of a photosensitive body is changed in the image forming frequency less than a fixed value, the charging quantity is not corrected by a charging charger, so that the generation of excess charge or the like due to the conventional correction of charging quantity for other causes can be prevented.

Title: Semiconductor memory circuit
Inventor: KIMOTO HISAMITSU
IPC: H01L21/8249
Filed: 1991-07-26
Abstract: PURPOSE:To shorten the access time when a reading and writing action is continuously performed for a memory cell in a semiconductor memory circuit. CONSTITUTION:When an input terminal 12A of a BiCMOS logical circuit 12 becomes a high level, an NPN transistor 122 in the BiCMOS logical circuit 12 becomes ON and a collector voltage is reduced. When the voltage between an emitter and a collector becomes 0.7V or below, the switching time of the NPN transistor 122 becomes long. On the other hand, since an N channel FET 101 becomes simultaneously ON, the delay of the switching time of the BiCMOS logical circuit 12 can be compensated. Therefore, the action time of the precharging circuit composed of P channels FET 13 and 14 is also shortened. For this reason, the continuous access can be performed for a memory cell 11.

Abstract: PURPOSE:To improve the working efficiency while enabling the chip characteristics to be measured accurately under no influence of any stain by a method wherein dummy probes mechanically rub over the surface of pads or bump electrodes to expose new metallic surface without fail before regular probes to measure the electric characteristics are brought into contact with the pads or the bump electrodes. CONSTITUTION:While regular probes 4 are brought into contact with gold bump electrodes 9a to measure the electric characteristics of a semiconductor chip 7a, dummy probes 5 are preceding to be located on the other gold bump electrodes 9c of another semiconductor chip 7c. Said probes 4 and 5 are advanced by the movement of a semiconductor wafer 8 with their relative positions kept unchanged so that the dummy probes 5 may mechanically rub over the contact surfaces of gold bump electrodes 9a, 9b, 9c successively to remove any surface stain. When the dummy probes 5 are brought into contact with the surface of gold bump electrode 9c, any pollutant 10 is swept up toward the end part of electrode surface by the dummy probes 5 while a part of the surface of gold bump electrodes 9c is simultaneously shaved off to expose the cleaned up surface 11. Through these procedures, the probes 4 advancing together with the movement of wafer 8 can output accurate measurement data.

Title: Hollow cylindrical body for embedding by casting and production thereof

Filed: 1988-08-26
Abstract: PURPOSE:To facilitate production and to improve the adhesiveness to a 2nd casting by forming the adjacent shape parts of the plural projections of a hollow cylindrical body produced by substitution of an expendable pattern by a molten metal to a dovetail grove shape. CONSTITUTION:The projections 3 are formed on the outer peripheral surface of the hollow body 1 for embedding by casting which is the 1st casting in such a manner that said projections have substantially the shape of dovetail grooves 6 and, therefore, Al 10, etc., are so cast as to enclose the projections 3 if said hollow body 1 is embedded by casting of Al, etc., of the 2nd casting by using said projections as inserts. The plural spherical projections 3 which are hermispherical are integrally formed on the outer peripheral surface of a single straight cylindrical part 2 and the 1st casting is not deviated from the 2nd casting in either of the vertical and lateral directions. The inside peripheral part of the cylinder block 10 which is the 2nd casting attains the higher tight contact state while enclosing the projections 3 even if the cylinder liner 1 which is the 1st casting is expanded by heating and, therefore, the heat conduction routes thereof are not shut off in case of using such integral casting structure for, for example, an internal combustion engine. The heat of the cylinder liner 1 is thus effectively transmitted to the cylinder block 10.
